Via a staircase with 252 steps hewn out of the rock, you come to the galleries, which are open to visitors (1km). The cave features rich and varied concretions that are reflected in the pools of water - fed by waterfalls. Some vaults have a geometrical partitioning of fine stalactites either coloured by metallic oxydes or of an immaculate white. As the exit is in the middle of scrubland, visitors are driven back to the foyer on the tourist train.
